Application led December 5, 1911. Serial No. 664,117. I

To all trimm t may concern Be it.' known that I, Jason H. GREEN-Sinnn'r, a citizen of the United States, re

,isi-ding at indianapolis, in the county of Marion and Sta-te ofindiana, have invented a new and useulBoX-Wlachine, of which thefollowing is a. specification.

The object of my invention is to provide means, in a box-blank makingmachine, t0 automatically space the several cleats'of each blank and to'also automatically space and gage the first cleats of each blank fromthe 'lastcleats of the finished blank.

The accompanying drawings illustrate my invention. j

Figure 1 is a vertical section of a machine, having the generalcharacteristics of the inachine lshown in my Patent 985,999., datedMarch 7, 1911, equipped with my present in.

mechanism 11, which may be of Well known form. lDelivei-ino to andextending from t n a the anvil 10 are cleat guides l2, l2. Trav ersingthe initial end of each cleat guide is a preliminary cleat Jfeeder 13which is conveniently an endless chain so :formed as to be capable ofdriving the cleats 14% tl'irough the guides toward the stapling plane.Feeders 13 are driven from the main drive shaft 15 by a friction train1G by means of which they may be caused to exert a driving eilect uponthe cleats at greater speed than the The' primary feeders 1--T arearranged one 'adjacent each cleat guide 12 lbeyond the In the `formshown in the present drawings each primary feeder 17 a spurred endlesschain arranged to, engage the cleats 1l and [these chains are advanced.ste rb f-ste b i a geartrain 19 acted on by a paWl-arm 20,

. pitman 21 and eccentric21.

'Arranged alongside each cleat guide 12 is a spacerfinger 22 similar tothe spacing llinger shown in Patent 958,996, and capable oflateralprojection into and out of the adjacent cleat guide as Well asmovement lengthwise of the guide. Eachnger 22 is pivotally connected tothe upper end of an arm 23 carried by a rock-shaft 24 and is alsoprovided With tivo cam surfaces 25 and 26 adapted, when brought intoengagef ment With pins or rollers 27 and 28, respectively, to shift thespacing-tip 22 of the linger into or out of the cleat guide. In order toprevent the tip of each spacing finger from rubbing against the cleatson its return movement. and to hold it in place .on its forwardmovement, I provide a cam track 29 of Well known form, in whichwilltravel a pin 31 carried by finger 22.

'In order to permit the insertion of the spacing lingers into theircleat guides in front of each oncoming cleat, it is necessary that theoncoming cleat be retarded and for that purpose I arrange, adjacent eachcleat guide and in front of the stapl'ing plane, a retarder finger 35which is adapted to lbe projected sidewise into theadjacent cleat guidein front of a shoulder 36 (on the forward end of the cleat) as shown inlFig. 2. Each finger 35 is normally urged into the adjacent cleat guideby a spring 37 and is driven out of the cleat guide by an,v

actuator cani 38 on a rock-shaft 39 to which is attached an arm 41.Pivoted to arm 41 is a link`42 to Which is connected', by a pin and slotconnection 43, a pavvl le which pivotally depends from one arm of abell-crank lever Connected to the other arm of lever is a link 46 whichis also connected to a lever 47, one arm of which is held against thepassing cleats 14 by a spring 43 so as to normally hold paivl 44 out. ofenga gement by a continuously rotating ratchet wheel 4:9 driven by anysuitable driving train, the arrangement being such that, as soon as acleat passes lever i, the trailing arm of that lever will drop inbehind'the cleat. and project pavvl le into the teeth of wheel 4.9, whereuponsaid Wheel will serve` to drive link l2 to the right (Fig. 3) and thusrock shaft 39 so as to cause its cam 3S to Withdraw linger 35 from in`front of 'the arrested cleat 18. in the meantime, the

be controlled' automatically, I :provide a the number of cleats in anyseries in the def sired blank and there are as many pins 53 as there aregroups of teeth.

Arm 51 may be withdrawn from arresting position by the following means.Connected to said arm 5l is a link 6l which is also connected to abell-crank lever G2 to which is connected an actuator bar G3 provided atits free end with a tooth G4 arranged above a continuously rotatingratchet wheel 65. Tooth 64 is normally held out ot the path of the teethof wheel '65 by a light/ spring 66 but may be readily projected into theteeth of the wheel by means of a finger 67 which is projected dowrmardlybv a spring 68 and normally trails upon the box blank material, as shownin Figs. l and 1i, the arrangement being such that, when the materialhas passed from beneath linger 67 it will be forced down upon bar 63 anddrive its tooth 64 into contact with the teeth of Wheel G5, whereuponbar 63 will be driven material guide, a continuouslyT rotating drivingmember, and means controlled by the passage of material through thematerial guide forA intermittently connecting the actuator 'with thedriving member to withdraw the interrupter from the material guide.
